Question 1007801
A cyclist bikes at a constant speed for 25 miles.  He then returns home at the same speed but takes a different route.  His return trip takes 1 hour longer and is 30 miles.  Find his speed?
<pre>Let speed be S
Then time on outbound trip = {{{25/S}}}
Time taken on return trip = {{{30/S}}}
Time equation formed: {{{25/S = 30/S - 1}}}
25 = 30 – S ------- Multiplying by LCD, S
S, or speed = 30 – 25, or {{{highlight_green(5)}}} mph
